Abstract (en)
[origin: EP0547959A1] A device is described for separating hydrogen from gaseous mixtures containing it or for purifying gaseous hydrogen, comprising an external casing (2) filled with a plurality of tubes (3) consisting of a suitable palladium-based alloy, closed at one end (4). These tubes are fixed in a substantially leakproof way, open end side (5) to a least a part of one base (6) consisting of a metal alloy whose composition is such that its coefficient of expansion under hydrogen is substantially equal to that of the alloy of the tubes. The base can be of a single component consisting of the above alloy or it can contain a collar, with substantially the same composition as that of the tubes, which adheres to the latter via an autogenous weld. Application to the electronics industry especially. <IMAGE>
